About ZoneKit

ZoneKit is a free collection of time and time-zone utilities. We built it because the existing options either bury simple tools under cluttered interfaces, demand a sign-up before showing you a clock, or feel stuck in 2005. We wanted something fast, clean, and trustworthy.

What we offer

• World Clock — see the current time in any city, side by side, with day labels for cities that are already on tomorrow.
• Meeting Planner — find the overlap of working hours across multiple time zones at a glance, with a colour-coded grid that makes "works for everyone" obvious.
• Time Zone Converter — answer "what's 3 PM New York in Tokyo?" instantly, with cross-day shifts highlighted so you never schedule on the wrong day.
• Countdown Timer — track days, hours, and minutes until any future date, with shareable links so you can send a countdown to anyone.

How it works

We've deliberately kept the site lightweight. No pop-ups, no sign-up walls, no scripts that follow you around the web, no notifications begging you to come back. Your preferences — the cities you've added, your format choice, your saved countdowns — stay on your own device. Clear your browser data and the site forgets everything. There's no copy of it on our end, because we don't store it anywhere.

For the time calculations themselves, we rely on the same time-zone information your phone and computer already use. That means our times stay accurate automatically through daylight saving transitions and the occasional zone rule change — whenever your device gets a software update, our clocks benefit too. You don't need to refresh, reconfigure, or do anything.

Who we are

ZoneKit is built and maintained by a small independent team. We're not VC-funded, we don't have an enterprise plan to upsell, and we don't sell or share your data. The site is supported by display advertising.
